The performance of the well-established Mitutoyo Holtest series, well-known for
their highly stable three-point self-centering action, has been further enhanced
by coating the contact surfaces with titanium nitride.

Holtest
• Titanium-coated measuring pins provide excellent durability and impact
resistance and allow the instrument to measure right to the bottom of a
blind hole.
• Digital display with quick-action lever operation enables easy and speedy
measurement.
• Built-in Absolute System eliminates the necessity to set the origin point
at every power-on. The system is also immune to over-speed errors, thus
increasing the reliability of measurement.
• A tolerance judgment function is built in to allow GO/NG judgment based
on user-defined upper and lower limit settings.
• Titanium-coated measuring pins provide excellent durability and impact
resistance and allow the instrument to measure right to the bottom of a
blind hole.
• DIGIMATIC Holtest is equipped with a digital display for easy readability.
• ABS (absolute) and INC (incremental) measuring modes promote highly
efficient working.
• DIGIMATIC Holtest is compatible with statistical process control systems
and measurement support systems.
• DIGIMATIC Holtest is able to memorize two preset values for the datum
point.
• Function lock key prevents changing the datum point accidentally.
• Affordably priced, popular Holtest
• The anvils and cone are made from an alloy tool steel with a hardness of
HRC60.5 or more.
• Versions for measurement of special forms can be custom manufactured
in tool steel.
• Titanium-coated measuring pins provide excellent durability and impact
resistance and allow the instrument to measure right to the bottom of a
blind hole.
• Three-point design assures self-centering action for stable measurements
in the range above 8mm bore diameter.
• Bore micrometers fitted with the constant-force ratchet enable consistent
measurements with minimum variation between operators.
Titanium Coated Measuring Pins
Measuring a Blind Hole
Applying a titanium-nitride coating to the contact faces of the
measuring pins has improved durability and abrasion resistance.
With this coating the pin material can be changed from carbide to
hardened steel to provide extra toughness for preventing a contact
face being chipped during measurement.
Measuring pins attached to the anvils permit measuring the
diameter of a blind hole almost down to the bottom.
*The Holtest type II does not use measuring pins.

Features
•Used for quick zero adjustment of dial bore
gages, Holtest, and inside micrometers.
•Actual inside diameter is marked on each
ring.
•Ceramic Setting Rings are also available.
Anticorrosion treatment is usually not
required when handling Ceramic Setting
Rings, resulting in simple maintenance and
storage.
